First claim

Opening claim text (preview).

The invention claimed is: 1. A drum brake assembly ( 10 ) for a motor vehicle, the drum brake assembly ( 10 ) having: a brake drum housing ( 16 ); at least one brake shoe ( 26 ); a brake lining ( 18 ); wherein the brake lining ( 18 ) is arranged at an inner circumferential face ( 24 ) of the brake drum housing ( 16 ) and the brake shoe ( 26 ) is displaceable relative to the brake lining ( 18 ), so as to contact the brake lining ( 18 ) during braking, and wherein a material of the brake shoe ( 26 ) has a larger coefficient of thermal expansion than a material of the brake lining ( 18 ) and/or of the brake drum housing ( 16 ). 2. The drum brake assembly ( 10 ) according to claim 1 , wherein the brake lining ( 18 ) comprises a friction material. 3. The drum brake assembly ( 10 ) according to claim 1 ; wherein at least a contact surface ( 28 ) of the brake shoe ( 26 ) that is configured to contact the brake lining ( 18 ) during braking is made from a material that is different from the material of the brake lining ( 18 ). 4. The drum brake assembly ( 10 ) according to claim 3 , wherein at least the contact surface ( 28 ) of the brake shoe ( 26 ) comprises a material that is harder than the material of the brake lining ( 18 ). 5. The drum brake assembly ( 10 ) according to claim 1 , wherein the brake shoe ( 26 ) comprises a metallic material and cast iron. 6. The drum brake assembly ( 10 ) according to claim 1 , wherein the brake drum housing ( 16 ) comprises a material that is different from the material of the brake lining ( 18 ) and that is lighter than the material of the brake lining ( 18 ). 7. The drum brake assembly ( 10 ) according to claim 1 , wherein the brake lining ( 18 ) forms a continuous ring extending along the inner circumferential face ( 24 ) of the brake drum housing ( 1816 ). 8. The drum brake assembly ( 10 ) according to claim 1 , wherein the brake lining ( 18 ) comprises a number of brake lining segments that are arranged in a ring-like manner along the inner circumferential surface ( 24 ). 9. Brake drum assembly ( 14 ) for a motor vehicle, the brake drum assembly ( 14 ) having a brake drum housing ( 16 ) and a brake lining ( 18 ), wherein the brake lining ( 18 ) is arranged at an inner circumferential face ( 24 ) of the brake drum housing ( 16 ), wherein a brake shoe ( 26 ) is displaceable relative to the brake lining ( 18 ), so as to contact the brake lining ( 18 ) during braking, and wherein a material of the brake shoe ( 26 ) has a larger coefficient of thermal expansion than a material of the brake lining ( 18 ) and/or of the brake drum housing ( 16 ).
